Flow regulators
Flow regulator is a unit designed to provide constant inflow no matter what the level of water is at the outflow slot. This unit is used in water systems to regulate rainwater flow. Usually these are used in such constructions as:
- stormwater distribution unit
- storm overflows
- rainwater retention tanks
- sewerage system of rainwater
- units purifying water

Regulators with flow over 50l/s have outside diameter over 600 mm
Regulators stabilising the flow which we offer are designed and fitted to individual needs of clients namely to the required flow and the backwater accumulation height.
They consist of:- Inlet connectors
- Swirl chamber
- Slot to attach the piping
- OOptional flange for the tank
Preformance graph of this regulator. Flow = 20 l/s Water column height = 1 m
Operation:
Hydrostatic pressure in the controlled tank rises commensurately with the liquid column height. The
generated whirlpool in the swirl chamber rises with the rising pressure. If there is a rise of whirlpool
in the chamber, it causes a return flow which consequently arrests the flow. The return flow does
not exceed the border flow upto provided height.
Materiał:
Flow regulator is in whole made of stainless steel type 304 or other depending on the client's
requirements.

VERTICAL FLOW REGULATOR RSTWOS
Increased or heavy rainfall requires precision in management in order to prevent installation overload and flooding. It is necessary to to make use of the retention and flow regulation techniques. RSTWOS regulator allows flow regulation thanks to whirlpools which are the result of the difference between the pressure on the inlet and at the outfall. The high difference causes whirlpool, which automatically reduces the flow and its cross-section. Regulators RSTWOS are wet installed in retention tanks of rainfall or sewage. Biocent regulators are made of stainless steel INOX 304L, thickness 2 to 3mm depending on the size of the unit. This allows high endurance of the regulator.

Construction- Flow regulator is in whole made of stainless steel type 304 or other depending on the client's requirements
- Instalation metal plate to fix the device
- Main swirl chamber
- Installation channel with the lifting handle
- Handle for fitting into the wall
Installation:
Vertical flow regulator is mounted directly to a smooth, concrete wall. It is fixed to handles, which
are fixed to the wall with anchorings beforehand. The height of the lowest inlet part has to be at
least 40 cm from the bottom. This regulator can adjusted to be mounted in round wells or can be
delivered already mounted in a PEHD/GRP well.

FLOAT FLOW REGULATOR RPWO
Float flow regulator is a regulating unit fixed at the side of the water pressure and regulated by a special float.
It is characterised by a compact construction and a high level of regulation +/- 5% of the assumed outflow. Regulator float may be placed at the front, from the left, or from the right depending on the building conditions.
Additional value of this regulator is the possibility to change the flow by +/- 15-20%. Moreover it can be equipped with unit identyfying contamnations blocking the flow, and getting rid of them.
Outflow float regulator is made of stainless steel combined with high classs of synthetic materials like POM or PA.
| Regulator type | Outfall slot diameter | Flow |

Preformance graph of this regulator. Flow = 20 l/s Water column height = 1 m
Operation:
The float connected with the arm moves with the water flow. The arm controls the decapitator that
reduces the flow or enlarges the oufall slot. This type of operation ensures high precision of this unit
and guarantees the real flow of +/- 5% with any backwater accumulation height. The cross-section
of the inlet slot is adjusted to the slightest movements of the float.
Installation:
This unit has to be mounted with anchoring directly to a smooth, concrete, vertical wall. There is an
option of mounting in round wells.
